I too experienced the same thing. We frequently grep through 6,000 or so small files, and current kernels take 50% longer than 1.2.13; in my case we also moved to elf only, which I figured accounted for some of it, but it's a problem for us.

I'll perform tests too, if someone tells me what. Maybe Bash or Grep needs to be recompiled with newer libraries (?) I'm running libc-5.2.18 now, but am downloading 5.3.9 in hopes that things improve.
